Hi - Recently upgraded to TurboCad Pro Platinum 2017. Initial start of the program resulted in a message something like "your video card is supported, for improved performance and speed change native draw to Redsdk" which I did. For information, my video card is an older (read legacy) AMD Radeon HD5700. Zooming in or out often causes the display to produce multiple images. Entities are drawn at different sizes and if turned on the grid will be garbled. I have attached a simple drawing of a circle which I zoomed in and out a few times with this result. Changing to GDI in native draw does not have this problem. TurboCad 17 does not have this problem.
I began to suspect that my video card was the problem so I loaded 2017 64 bit to my laptop, an ASUS Intel i5, 6 GB ram, onboard Intel video. RedsdK on this machine is slow as molasses, even though I got the same message that my video card is supported and for more speed better performance, change to RedsdK. I have verified that the video is set to its highest performance. GDI works well on this machine for native draw. Version 17 on this machine works well with both GDI and Redsdk.
As I am trying to use 2017 to the best of its capabilities do I just go back to GDI for native draw, look for a better video card or some other option. I was under the impression that Redsdk was the current thing.
Thanks for reading
